G1: This strategy centers around Germany’s ability to build from Western Germany into SZ 112. Build an AC and two transports; or if you’re feeling less adventurous, build an AC and a destroyer and sub (or save the 6 IPCs). Use the bomber, 4 fighters, and 3 tac bombers plus your starting subs in the Atlantic to clear the SZs around Britain.
You guys must have loaded dice to think you can send all of your air force against UK and still have enough fire power to take out France. Sitting in France is 7 inf, 2 art, 2 tanks, 1 fighter. The most land units Germany can bring is 6 inf, 4 mec inf, 2 art, 5 tanks. That would be 8 (1s), 4 (<2), 5 (<3) against 9 (<2), 2 (<3) and 1 (<4). If dice doesn’t go your way (and it never does for me, esp in the early rounds) then you don’t take France and have a much closer enemy than UK.
